What you are talking about doing is using DHTML to modify your HTML document. This is a VERY broad subject, and the two specific questions that you have asked can both be accomplished in several ways.
As far as the loading of different key pads, I think I would probably create an IFRAME in my HTML document and control its src property in the onClick event of your control buttons. Maybe something like this:

As far as highlighting a button, it depends upon whether you are using graphic buttons or HTML buttons. In case of graphic buttons, you need a new GIF to show the highlight and you simply replace the image's src property. In the case of an HTML button, you can change its background color using style sheets.

Thanx Bodie
your first idea worked.
i will make my second question more clear . Every button(It actually is a href element) has 2 gif files ( one is button press down image , the other is button up image ) , i use these 2 images to gain 3D effect( Add OnMouseDown="showImage(...)"...) . when i want to hightlight specified button , i not only change its button up image , but also want to change its MouseDown behavior on the fly . Can this be done by using javascript ?

Thanx again , specially to Bodie
